On Leah Remini: Scientology and the Aftermath, Remini discussed with journalist Tony Ortega Scientology’s drug rehabilitation program, Narconon. Though the program advertises extremely high success rates, as much 91 percent on its website, there are no studies to support those numbers and as Ortega stated, “In fact, we have documents showing their own attorneys saying ‘We have to stop saying that, it’s not true.'”

Ortega also went on to explain that the Narconon facilities are essentially a front for conversion, saying, “Scientology advertises that it’s going to give you individualized drug counseling. And they’re very careful never to tell you that you won’t be talking about drugs at all. You’re just getting Scientology training.”

According to Ortega, people who go to Narconon are put in harm’s way with a risky detox program. With people coming in that have compromised immune systems and livers they, “then go into this 25-day sauna program where they’re being baked, you know, four or five hours a day. Well, these parents, before sending their loved ones to Narconon should be checking it out before putting them into a risky situation. It’s risky, it’s bad, and several people have died.”

With the deaths of patients at these facilities (including four at the Narconon Arrowhead, Oklahoma facility), this Aftermath episode shed light on the questionable legitimacy of Narconon and its rehab program.

For the record, Scientology disputes the claims on Remini’s show. Their response can be read here.
